Metal and Wire Tube Bending: Industrial Expertise in Deformation
STN is a leading specialist in metalworking. Our core business? Tube bending and wire forming. Thanks to our ultra-modern machinery, we offer a complete metal forming service for industry.
Cutting-edge technology : Numerical Control and Precision
The bending process consists in deforming the material to obtain a perfect curve.
Specialized equipment: We use CNC machines to produce complex bends with the utmost precision. Unlike approximate manual bending, digital bending guarantees repeatability.
Mastered techniques: We excel in mandrel bending (to avoid crushing in the bending zone), roll bending (for large radii) and cold bending. Cold bending preserves the mechanical properties of the metal, unlike hot bending, which modifies the structure.
Tube integrity: Our know-how enables us to deform a tube without wrinkling the inside or excessively thinning the outside (elongation control).
Processed materials and shapes
We work with a wide variety of materials and profiles.
Materials used: Whether you need to bend copper, aluminum,stainless steel (inox) or a specific alloy, we adapt the tooling to your needs. Steel tubing remains the main demand, but we also handle softer metals.
Profiles: We work with round tubes, as well as square, rectangular and ovoid metal tubes.
Surface finish: We take great care to ensure that no marks detract from the aesthetic value of the part, especially in the case of visible metal components.
Differences between bending and folding sheet metal
It's important to distinguish between these two professions.
Tube bending: This involves forming a curve on a hollow (tube) or solid (wire) profile. This often requires a mandrel and rolling to support the material.
Sheet metal bending: This technique is applied to flat sheet metal to create sharp angles or folds. STN is a metal bending company that also masters laser cutting and metal cutting (via our sheet metal bending expertise), offering a global solution. Whether you need to bend sheet metal or tube, we've got the answer.
